leaks in your ac system
Your air conditioning unit will stop working under low Freon conditions in most times is caused by a leak in your system,do not assume you know what is wrong,and most of all do not tell the technician you know what is wrong you will further delay the issue.
Vibration,improper mounting,wear,and tear can cause your unit to leak
air conditioner is responsible for keeping the interior cool and comfortable on hot days. However, in order to do that, you need the right level of refrigerant in the system. If your refrigerant is low, the air conditioner may blow warm or hot air. A special switch is designed to sense when there isn’t enough pressure (or when pressure is too high) and disengage the AC compressor clutch, which operates the compressor to pressurize the system.
Causes of low refrigerant
There are a number of potential causes for low refrigerant in your car’s AC system. Some refrigerant is lost naturally over time. It takes years, though, so if your car isn’t that old or the system has been recharged recently and is now blowing warm air again, chances are good that you’ve got a leak somewhere.
There are two causes of AC system leaks – age and moisture. While much of your air conditioning system is made of metal, including the high pressure lines, rubber is still used throughout. You have rubber O-rings, grommets, lines and more. The problem here is that rubber degrades over time and with exposure to heat and moisture. As that wear accelerates, the affected part will fail. Something as simple as a degrading O-ring can cause you to loose refrigerant surprisingly quickly.
